About Imperial Gallons
A US imperial gallon (UK gal) = exactly 8 imperial pints or 10 lb of pure water at 62°F ≈ 4.546 L - about 20% larger than the US liquid gallon (3.785 L).

About Cubic Meters
A cubic meter (m³) is the SI derived unit of volume - the volume of a cube with sides of one meter - equal to 1,000 liters. It is the standard international unit for large fluid volumes, solid materials, and gas quantities. Concrete production and placement is measured in cubic meters; river discharge is reported in cubic meters per second (m³/s, or 'cumecs'); shipping container capacity is quoted in cubic meters; and natural gas is traded in standard cubic meters. An Olympic swimming pool holds 2,500 m³. One cubic meter of water has a mass of exactly 1,000 kg (one metric tonne).
